Pros
The people are wonderful, for the most. Of course, there will always be jerks wherever you go. But overall, UPS hires good people that know how to "adult" in tough situations. Old school manners prevail, with men holding doors and waiting for women to enter and exit elevators first - sometimes to comical effect if the woman in question is not used to such gentlemanly behavior (me). Beautiful campus, decent cafeteria, steady and dependable organization.
Cons
Dependability sometimes breeds complacency, so long term employees tend to coast in their jobs. The old-timers someone just hold on until retirement (at 55 if you have been an employee for 25+ years!) New employees should not expect that kind of retirement. Contractors do a LOT of work for UPS - but of course - you can be let go at any moment (a downside of contractor life). For the most part, contractors treated fairly, although there is the typical "smoke and mirrors" / red badge crap that still goes on (honestly no different than other contract positions I've had). Also, like many companies-UPS is extremely focused on attracting millennials-often at the expense of neglecting older employees. This is definitely creating some resentments in the troops.
